FURRlNG-STRIP FOR WALLS OR CEILINGS.

SPECIFICATION forming part of Letters Patent No. 400,521, dated April 2, 1889. Application filed November 28,1888. Serial No. 292,049. (ITO model.)

To all whom it may concern:

Be it known that I, J E oMn TVVIOHELL, a citizen of the United States, residing at Kan= sas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Furring-Strips for Walls or Ceilings; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in furring-strips for walls or ceilings.

The object is to provide a simple, effective, and inexpensive device for securing metallic lathing or corrugated metal sheets to the wall or ceiling to render the building fire-proof.

In the accompanying drawings, Figure 1 represents the furring=strip secured to a joist and the laths in position therein. Fig. 2 is a transverse section through the line 00 so of Fig. 1.. Fig. 3. represents the furring-strip secured to a stud, and Fig. 4: represents the furringstrip secured to a metallic ceiling.

A represents the body of the furring-strip; and it consists, preferably, of a strip of bandiron or other sheet metal. At suitable intervals along one edgeviz., the edge which is intended to be placed uppermost or outermostthe strip A is provided with prongs 13, formed by portions of the strip A, partially severed therefrom by slanting cuts and turned laterally at right angles to the strip in position to be driven into the joist O or stud D, or through the sides of one of the corrugations e in a corrugated metallic ceiling, E. When secured to the joist or stud, the body of the holder is intended to stand at right angles to the plane of the ceiling or wall.

The inner edge of the furring-strip is provided with a series of prongs, F, formed by portions of the strip itself, partially severed therefrom by slanting cuts, and bent away from the edge of the strip far enough to receive between them and the edge of the body portionA a metallic lath, G. The furring= strips are intended to be employed in series, one to each joist, or as often as found expedient, and a single lath will extend across two or more of the holders, as the case may be. When secured in position and the plasfor applied to the lath, a circulating-air chamher is formed between the joists and the plaster, and the proof against fire may be still further augmented by the employment of the metallic ceiling between the joists and plaster.

The furring-strips may be out from sheets of metal or from strips of band metal by a single stroke of the cutter, and the prongs afterward bent and opened to adapt them to the purposes for which they were intended. Said strips may also be further provided with holes m to receive nails or screws as additional fastening.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A furring-strip consisting of a strip of metal having retaining-prongs cut from one edge and lath-holding prongs out from the other edge, substantially as set forth.

2. The herein-described furring-strip, consisting of a strip of sheet metal having a se-. ries of pron gs partially severed from one edge and turned out of the plane of the body portion of the holder to enter a support, and having a series of lath-holding prongs partially severed from its opposite edge and bent away from the edge to receive the lath, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

JEROME TWIOHELL.
